assignmto Electrolux Corporation, Dover, Del., a corporation of DelawareApplication July 27, 1938,. Serial'No. 221,509 In Germany August 2, 19373 Claims. -(Cl. 285-21) My invention relates to vacuum cleaners and moreparticularly to an improved suction nozzle for use in connection with avacuum cleaning unit of the type wherein means are provided fordetachably connecting the suction nozzle to a hollow rigid handle and aflexible hose.

With a nozzle of this type it is desirable to have the hollow handleextend therefrom at an angle of approximately 45 when the nozzle isbeing used for cleaning a floor. ,However, when it is desired to cleanunderneath 10w furniture, or to clean a surface which is above the levelon which the operator is standing, it is preferable to have the handleextend substantially parallel to the floor or other surface beingcleaned. Heretofore, this has been accomplished by connecting the handleto the nozzle by means of some type of pivoted or swivel connection.However, this entails a rather expensive construction and also tion willbe apparent from the following description, considered in connectionwiththe accompanying drawing, which forms a part of this specification, andof whichi Fig. 1 is 'a cross-sectional view of anozzle in accordancewith my invention; and

,Fig. 2 is a rear view of the nozzle shown in Fi ure 1. A Referringto'the drawing, reference character Ill designates a hollow body formedwith a lower elongated inlet opening II, which may be surrounded bybrush bristles l2. A strip of rubber l3 .may be provided around the bodyl and serve both as abumper and as a means for supporting the bristlesH. The space-within the body ID, to which the elongated inlet ll opens,converges to a centrally located circular opening It in the upper faceof the body In.

Secured to the body by means of screws I5 is a hollow connection memberl6, Member I6 is formed with two intersecting bores, one of whichis'bounded by a slightly conical surface l1, while the other is boundedby a similar conical surface l8. These two surfaces intersect along aline I! which forms a portion of an ellipse. A hollow rigid handlemember 20 has one end formedslightly conical and is adapted to bereceived within either of the bores. As shown in solid lines in Fig. l,the handle is received in the bore which is bounded by the surface llandin this position extends at about 45 to the surface 6 with which thenozzle is in contact. It will be seen that in this position the handle20 completely blocks off the bore which is bounded by the surface I8. Ifit is desired to use the nozzle under low furniture or for any other usein 10 which the handle should extend substantially parallel to thesurface being cleaned, the handle is removed from the position shown infull lines and placed in the position shown if. broken lines, where itengages the bore which is bounded by the surface l8. In thislatter'position it completely blocks off the other bore.

in order toprovide a somewhat better bearing for the handle in thenozzle when it is inserted in the full line position, which is theposition in which it is chiefly used, a supporting member 2| may beprovided-which engages the lower upper side of the handle. The surface22 on the member 2| which contacts the handle is made slightly conical.As will be seen from the drawing the 26 member 2! is further providedwith a surface contacting the under side of the handle when it isinserted in the nozzle in the broken line position, thus forming animproved bearing for the handle in said position. The member 2! shouldbe com- 80 paratively narrbw so as not to interfere materially with theflow of air when the handle is in the broken line position.

It will thus be seen that I have provided a nozzle and handle which mayhave different relative 86 angular positions without requiring the useof any pivoted joint. While I have shown one preferred embodiment in myinvention this has -been done for purposes of illustration only, and

has not intended to limit its scope, which is to 40 be determined by theappended claims viewed in the line of the prior art.

vI claim:

'1. In a suction nozzle, a hollow body formed with an inlet and aplurality of outlets, said outlets being in the formof mutuallyintersecting bores, and a conduit member having an open end and a solidside wall receivable in any of said bores, the relationship of theintersecting bores being such that when said conduit member is receivedin any bore the solid side wall thereof extends across the remainder ofsaid bores to thereby close. the latter.

2. In a suction nozzle, a hollow body formed with an inletandtwointersecting outlet passages, a conduit member receivable in eitherof said passages, the relationship of the passages being such that-whensaid conduit member is received in either passage it blocks 01f flowthrough the other passage, and a projection within; said hollow' memberprovided with a surface which is aligned with the interior surface ofone of said passages sowasto contact and support said conduit memberwhen the latter is received in said one of said passages.

3. In a suction nozzle, a hollow body formedwith an inlet and twointersecting outlet passages,

, either of said passages.
